Making use of the grid in Beijing, a dual-source trolleybus was developed, and achieved driving it by battery packs in off-grid area. Because of using a composite power system, the energy flow of the vehicle is multi-directional and multidimensional. To use the energy rationally, the energy flow was researched and energy consumption was tested with grid accessing The energy consumption distribution of dissipative components was obtained, influencing factors on energy consumption including vehicle body constru…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
